Today's molecule is very simple. We don't need a long complicated name this time; the short common name will do. (But you're welcome to supply the IUPAC name if you know it.) The trick here is to recognize why this molecular is important and then connect it to Wednesday's Nobel Laureate(s).
Here's a hint; with hindsight, this is probably one of the most undeserving Nobel Prizes in the biological sciences.
The reward (free lunch) goes to the person who correctly identifies the molecule and the Nobel Laureate(s). Previous free lunch winners are ineligible for one month from the time they first collected the prize. There's only one (Marc) ineligible candidates for this Wednesday's reward since many recent winners haven't collected their prize. The prize is a free lunch at the Faculty Club. I've been eating there a lot recently because we've had many meeting concerning an upcoming big event at the Faculty Club on this Friday evening. (My daughter, Jane, is getting married.)
